Hello,I just built a new PC, and everything works just fine except for one thing. When I take out my OS CD (Windows 7 Professional 64-bit) from the ROM drive, I get an error message and Windows will not boot. I forget the last digit but it is 0xf000000- In the BIOS I have it set to boot from cd-rom first, then hard drive. It will then check for a CD then hit the error message. I have tried changing it to hard drive first, but unless the OS cd in in the drive, it will not follow through. Any suggestions?
